Subject: mm/vma: fix mmap_prepare file handling, remove file_doesnt_need_get
Date: Thu, 17 Sep 2026 17:22:10 +0100

Patch series "mm: make VMA flag semantics explicit, eliminate VM_SPECIAL",
v3.

The VM_SPECIAL / VMA_SPECIAL_FLAGS mask conflates several unrelated
properties:

* Is this kernel-owned, whether MMIO, kernel-allocated pages, or ordinary
  pages a driver maps itself?
* Can it be expanded or merged?
* Is this a 'weird' case like mlock where migration might race and we
  'have' to set invalid flags to notify?
* Is it another 'weird' case where we just want to stop GUP from touching
  it?

Driver writers have often been confused about this, and who can blame
them?

It also interacts badly with the eternal edgecase known as hugetlb - which
sets VMA_DONTEXPAND_BIT but doesn't also want to be treated like a
'special' flag.

Another issue is that we cannot make sensible assumptions about flag use. 
It's not possible to assume VMA_IO_BIT means iommu because drivers abuse
it and mlock abuses it.

Special is also an overloaded term in mm.  VDSO and VVAR mappings are also
called 'special' but they're special in a...  special way.

Sometimes things are called special that are a subset of VMA_SPECIAL_FLAGS
(VMA_PFNMAP_BIT and VMA_MIXEDMAP_BIT for instance when it comes to zapping
or vm_normal_folio()).

There's a specific kind of special for THP too, which considers PFN map,
mixed map 'special' but DAX not.

It's all rather a mess.

This series brings some order to things by both limiting what drivers can
do with VMA flags and switching to using predicates that describe
behaviour, not arbitrary flags.

It establishes the invariant that only kernel-owned mappings may set
VMA_IO_BIT or clear VMA_MAYWRITE_BIT in an mmap hook, enforcing this by
validating VMA state after every mmap and mmap_prepare hook.

It updates usbmon and sg to mmap_prepare in order to do so, adding a new
mmap action for mapping discontiguous kernel pages, and has hfi1 and the
ALSA PCM status page map their pages eagerly instead.

It also establishes the invariant that VMA_MIXEDMAP_BIT be set when
mapping kernel memory, something that is usually the case but happens not
to be for some users - specifically defio, cmt_speech, uprobes and the bpf
arena, all of which are updated to do the right thing.

It replaces VM_SPECIAL and arbitrary flag tests with predicates that say
what is actually being tested:

   vma_is_kernel_owned()   Does a driver or kernel code manage a VMA's
                           life cycle?

  vma_is_fixed_mapping()   Is the VMA not permitted to be expanded or
                           merged?

     vma_is_persistent()   Do bytes written to the VMA stay written, and
                           bytes read stay the same unless userland changes
                           them?

         vma_can_merge()   Can the VMA be merged with a compatible
                           neighbour?

           vma_can_gup()   Can GUP obtain pages from the VMA, i.e. is it
                           neither a PFN map nor memory-mapped I/O?

Remaining raw VMA_IO_BIT, VMA_PFNMAP_BIT and VMA_MIXEDMAP_BIT tests
scattered across mm are also converted to predicates where it makes sense
to do so.

And also the opportunity is taken to eliminate THP's vma_is_special_huge()
which was an existing source of confusion.


This patch (of 39):

The map->file_doesnt_need_get flag is confusing and the existing
implementation has holes.

Drivers are permitted to change the owning file of a mapping.  If they do
so, they are required to take a reference on that file.

The mmap() operation which ultimately invokes __mmap_region() is
guaranteed to drop the refcount for the original file the mapping was made
under, but this is not true for the replaced file.

This has been addressed so far by tracking map->file_doesnt_need_get,
which is rather poorly named and unfortunately fails to correctly track
whether or not an additional put were needed in a number of cases.

Make life easier by removing this flag, and instead drop the reference for
both mmap_prepare and the deprecated mmap callback in a new function
put_map().

Track whether this needs to be done by aligning mmap_state with
vm_area_desc and store the original file in the map->file field, keeping
the updated file in map->vm_file.

In order to have the same behaviour for both types of hooks, only drop the
reference __mmap_new_file_vma() itself took in its error path, deferring
the replaced file's reference to put_map().

To make this work correctly, map->vm_file has to be updated before any
error handling, so update __mmap_new_file_vma() and call_mmap_prepare() to
set this field first.

Also when mmap_prepare() changes the file and is then merged, the
reference count also must be decremented, so update the logic to call
put_map() in this case too.

Also update __compat_vma_mmap() to manually perform this step for stacked
file systems using the compatibility layer, and update
compat_set_vma_from_desc() to replace vma_set_file() with a correct
refcount/file update.

No in-tree driver is impacted by the incorrect implementation of this
currently (no driver that does this is mergeable for one), so this does
not need to be a fix.
